The Rock Cycle | Posted in Earth and Space Science
It would be helpful to know what the students already know about rock formation and earth science in general.
If they have a basic understanding of rock formation then a hands-on activity identifying rock samples in a general way would reinforce their beginning understanding of the characteristics of sedimentary, metamorphic, or igneous rocks. The processes that form rock are more easily understood when looking at actual rocks.
Teaching for Conceptual Understanding in Science | Posted in Professional Learning
Currently, I am entering my 4th year of teaching 7th and 8th grade science. I’ve always felt that the traditional lecture format my department employs is not the most effective way to reach my students. I’ve added numerous lab activities in an attempt to promote deeper understanding. However, it wasn’t until I stumbled across this thread and read about conceptual understanding that I felt like this is the method that I should have been using all along. The shift to NGSS blends perfectly with this style of instruction and learning. I agree with Joyce in regards to covering the curriculum. We tend to sacrifice depth of learning in favor of squeezing everything in before the next round of state testing begins.
I have read and reviewed many of the resources provided in your book “Teaching for Conceptual Understanding in Science.” I felt the different instructional strategies listed in chapter 8 were extremely beneficial. I’m left with a few lingering questions though. Based on what I’ve read, teachers need to administer some sort of probe or pre-assessment to gauge students’ misconceptions or prior knowledge before planning instruction. Are these probes supposed to take the entire class period? If not, then how do you plan the day based on information you are gathering in a 15-20 minute time span? Using the conceptual thinking model how are teachers providing instruction for concepts that are completely unfamiliar to students?
Chem for those who do not like it | Posted in Chemistry
I think you have hit the reason for NGSS right on the head! The phenomenon approach to learning is what drives those students in the classroom. When teachers engage their students with phenomena they have a true curiosity or interest in the interest levels in the classroom drive up. Students are shifting from this rote memorization or even just learning content in isolation; to having a role and a mission of trying to figure something out. Chemistry is especially daunting in isolation. When you give students a task, then build a story around that task where now they need to know this information to complete the task. They will be more engaged. The hardest part is choosing a phenomenon that fits your students. You should figure out what are they interested in. What are things that would hook them? Once you get to know your students more you will know the types of phenomenon’s that will drive them.
